Check Digit Verification of cas no
The CAS Registry Mumber 49849-42-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,8,4 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 49849-42:
(7*4)+(6*9)+(5*8)+(4*4)+(3*9)+(2*4)+(1*2)=175
175 % 10 = 5
So 49849-42-5 is a valid CAS Registry Number.

Preparation of chiral 1,2,4-triazolium salts as new NHC precatalysts
Strand, Ragnhild B.,Solvang, Tina,Sperger, Christian A.,Fiksdahl, Anne
experimental part, p. 838 - 842 (2012/09/22)
The preparation of new chiral N,N′-disubstituted 1,2,4-triazolium based NHC salt precursors, Ia′ and Ib, from phenylhydrazine and l-phenylalanine is reported. The 1,3,4-trisubstituted triazolium salt Ia′ was obtained by a stepwise ring construction from l-phenylalanine via the corresponding imino ether and acetohydrazonamide, while a heterocyclic O-/N-heteroatom exchange strategy, based on a ring-opening/ring-closure of the oxadiazolium precursor, afforded the 1,4-disubstituted 1,2,4-triazolium salt Ib. The need for two different synthetic strategies is discussed.
